[jboss-jira] [JBoss JIRA] Created: (JBAS-3953) OracleDatabasePersistencePlugin does not override selectTimers(ObjectName containerId) - selecting persisted timers fails at startup
OracleDatabasePersistencePlugin does not override selectTimers(ObjectName containerId) -
selecting persisted timers fails at startup
------------------------------------------------------------------------------------------------------------------------------------
Key: JBAS-3953
URL: http://jira.jboss.com/jira/browse/JBAS-3953
Project: JBoss Application Server
Issue Type: Bug
Security Level: Public (Everyone can see)
Affects Versions: JBossAS-4.0.5.GA, JBossAS-4.0.4.GA
Environment: Oracle Database instead of HSQL-DB
Reporter: Gunnar von der Beck
Precondition:
-------------------
Configure the use of the OracleDatabasePersistencePlugin for EJBTimers:
<!-- A persistence policy that persistes timers to a database -->
<mbean code="org.jboss.ejb.txtimer.DatabasePersistencePolicy"
name="jboss.ejb:service=EJBTimerService,persistencePolicy=database">
<!-- DataSource JNDI name -->
<depends
optional-attribute-name="DataSource">jboss.jca:service=DataSourceBinding,name=DefaultDS</depends>
<!-- The plugin that handles database persistence -->
<attribute
name="DatabasePersistencePlugin">org.jboss.ejb.txtimer.OracleDatabasePersistencePlugin</attribute>
</mbean>
Error:
--------
The org.jboss.ejb.txtimer.OracleDatabasePersistencePlugin extends
GeneralPurposeDatabasePersistencePlugin and implements a method
public List selectTimers() throws SQLException;
In order to override the behavior of the GeneralPurposeDatabasePersistencePlugin the
correct signature must be
public List selectTimers(ObjectName containerId) throws SQLException;
Hence the following exception occurs when restoring persisted timers at server startup:
